11.9) Return Values

Returning a single value is easy, but what if you want to return two values? There are two main ways to do this, with a Tuple and with a dictionary.

With a tuple, it’s really easy to retrieve the individual values returned:

def three_ints():
    i=1
    j=2
    k=3
    return (i,j,k)
# function call
i,j,k=three_ints()

With a dictionary, you can identify the values better:

def coord_leeds():
    lat=53.8
    lon=1.5
    return {'lat':lat,'lon':lon}
# function call
coord=coord_leeds()
print 'latitude of Leeds:',coord['lat']
